Patent CA-2258081-A1 (CA)
Inventor: ZHDANOV MICHAEL S
IPC: A61B10/00
Filed: 1997-06-26
Abstract: A method of imaging an object, such as a diseased human heart or bone, in a nontransparent medium, such as the human body, involves placing an array of transmitters (12, 13) and receivers (14, 15) in operational association with the medium (16). The transmitters (12, 13) generate a harmonic (frequency domain) or pulse (time domain) primary EM field which propagates through the medium (16). The primary field interacts with the object to produce a scattered field, which is recorded by the receivers (14, 15). The scattered EM field components measured by the receivers (14, 15) are applied as an artificial EM field to generate a backscattering EM field. Cross power spectra of the primary and backscattering fields (in frequency domain) or cross correlation between these fields (in time domain) produce a numerical reconstruction of an EM hologram. The desired properties of the medium (16), such as conductivity or dielectric permittivity, are then derived from this hologram.
Patent CA-2259129-A1 (CA)
Inventor: MARTEL REMI
IPC: A61K31/70
Filed: 1997-07-25
Abstract: A cDNA clone encoding the human prohormone convertase PC5 was isolated from human adrenal gland messenger RNA. The deduced protein sequene would encode a 915 amino acid prepro PC5 which shares a very high degree of homology with the previously cloned rat and mouse homologues. PC5 mRNA is detected in multiple human tissues, including the brain, adrenal and thyroid glands, heart, placenta, lung and testes. PC5 mRNA was undetectable in the liver and is present at lower levels in skeletal muscle, kidney, pancreas, small intestine and stomach. Co-transfection of human PC5 and human prorenin expression vectors in cultured GH4Cl cells leads to secretion of active renin. The activation of human prorenin by PC5 is dependent on a pair of basic amino acids at positions 42 and 43 of the prorenin prosegment and occurs only in cells containing dense core secretory granules. Human PC5 was co-localized with renin by immunohistochemistry in the zona glomerulosa of the adrenal gland suggesting that it could participate in the activation of a local reninangiotensin system in the human adrenal cortex. PC5 is overexpressed in atherosclerotic coronary blood vessels. Silencing PC5 expression with a specific antisense oligonucleotide efficiently inhibited the proliferation of smooth muscle cells in culture. Furthermore, the antisense inhibited carotid stenosis in a carotoid injury model. These results indicate that silencing PC5 applies to the prevention of restenosis. PCs could be targets of choice for treating any proliferative diseases involving their action on a given growth factor. Finally, the antisense oligonucleotide PC5 is to be used for silencing the activity of this enzyme towards HIV gp160, since both coexist in CD4+ T lymphocytes and the viral glycoprotein is cleavable by PC5.

Patent CA-2273423-A1 (CA)
Inventor: STECKER DAVID W SR
IPC: A63B35/12
Filed: 1999-05-28
Abstract: The underwater dive vehicle disclosed has a selectively energizable propulsion unit for forcible driving the vehicle through the water and at least one resilient gas filled buoyancy element which is in open contact with the surrounding water when the vehicle is in the water. The volume of the gas in the buoyancy element provides sufficient displacement of the water to keep the vehicle afloat at the surface when unattended or to support a diver. When the vehicle is submerged water pressure will act directly upon and tend to compress the resilient buoyancy element and the gas contained therein. This reduces the volume of the gas within the buoyancy element and thus reduces buoyancy of that element. Seated housings such as those surrounding parts of the propulsion unit are filled with a non-conductive and non-corrosive liquid to prevent distortion and subsequent leaking of the seals, and non-moveable electrical components are encased in waterproof epoxy.
